JAMES WRIGHT MAOFARLANE, OF KINGSTON, SCOTLAND.

CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 752,572, dated February 16, 1904:. Application filed November 6, 1903. Serial No. 180,098. (No modali) To @Z whom, t may concern:

Be it known that I, JAMES WRIGHT MACEAR- LANE, a subject of the King of Great Britain and Ireland, and a resident of Kingston, in the county of Glasgow, Scotland, (whose postal address is 98 Dundas street, Kingston, Glasgow, Scotland,) have invented certain new and useful Improvements in Centrifugal Machines, (for which application for British Patent No. 9,184, dated April 23, l903, has been made,) of which the following is a specification.

My said invention relates to contrifugal machines of the suspended type driven by motors coupled directly to their spindles, and has for'its object the provision of means for easy disconnection and removal of the motor when it is desired to inspect or repair either the motor itself or the parts of the centrifugal immediately beneath it.

In the accompanying drawings, Figure l is a side elevation, partly in section, of a motor and so much of the framing and driving-spindle of a centrifugal machine as is necessary to illustrate my invention. Fig. 2 is a view similar to Fig. l of a modification, and Fig. 3 is a similar view of another modification.

In carrying out my invention instead of forming the motor as an integral part of the centrifugal machine it is made separate therefrom and coupled to the spindle thereof by any form of suitable clutch. The motor is according to one arrangement so carried by guides and a screw or screws or other form of lifting or moving device that it may be readily moved either vertically or laterally or both vertically and laterally, or according to a second arrangement it may be moved clear of the centrifugal machine by being carried so that it can turn about a horizontal or a vertical pivot, or similar provision for vertical or lateral movement combined with movement about the pivot may be made, or any other suitable arrangement of parts may be provided which will enable the motor to be moved as desired without requiring the use of means external to the machine to lift off the motor after disconnection from the centrifugal. Where electric motors are used, the manner of construction may in some cases be Vbeneath it.

such as will prevent the need for disconnecting the wire leads from the dynamo to the motor.

Three examples of the application of my invention are shown in sectional elevations on three accompanying sheets of explanatory drawings, throughout which like referenceletters indicate similar parts; but it is to be understood that my invention may be carried out in many ways without departing from the essence thereof, that essence being the provision of a device for moving the motor by means integral with the machine and without external aids.

In carrying' out my invention as shown in Fig. l the'centrifugal machine (of which only sufficient to illustrate my invention is shown) is of the typehaving arotatable inner spindle A. An electric motor B, which may be of any suitable known type, is connected to the spindle A by a clutch O, the upper portion, connected to the motor-spindle, having prongs D, which enter recesses in the lower portion, lconnected to the spindle A, so that the clutch can be disconnected by endwise movement of the motor B. Instead of forming the motor as an integral part of the centrifugal machine it is made separate therefrom, and it is carried on the framing E of the centrifugal machine by a screwed spindle G, secured to and extending down from the framing of the motor B through a pillar-guide H, made in the framing E, a nut .I on the screwed spindle G working in a gap K in the pillar-guide H. A tapered pin L on the motor enters a socket in the framing, and a stud M may be screwed into the end of the pin L to further secure the motor. When it is desired to disconnect and shift the motor B from the top of the centrifugal machine, the stud M is removed and the nut J is turned and acting on the screwed spindle G raises the motor B vertically. This disengages the two portions of the clutch C, and the spindle G and pillar H device serving as a vertical pivot the motor can then be swung about it into the position shown by dotted lines, where it is clear of the parts normally The screwed spindle G is made hollow and the electric leads P to the motor B are passed up through it.

As shown in Fig. 2, the motor B is carried IOO by having on it a part working in a slide in the pillar-guide H and provided with a nut J, gearing with a screwed spindle G in the pillar H, so that the motor B may be raised on rotating the spindle G. Ihe pillar H is hinged at its lower end, so that when the motor has been raised it can be swung over laterally into the position shown in dotted lines, and thus expose the upper end of the spindle A. Holes are formed through the spindle N of the hinge, so that the electric leads P can be passed up through it to the motor B.

As shown in Fig. 3, the clutch C is a jawclutch of such a shape that it may be disengaged laterally, and the guide portion H and screwed spindle Gr are placed horizontally, the latter engaging a nut J on the bottom of the motor-frame B, so that on turning a handle Q on the spindle G the clutch C will be disengaged and the motor moved laterally to the position shown by dotted lines, as desired.

I claim as my inventionl. In combination with the framing and driving-spindle of a centrifugal machine, a motor for driving same, a clutch coupling the motor to the spindle, and a device for moving the motor, such device forming an integral part of the framing, substantially as and for the purpose described.

2. In combination with the framing and spindle of a centrifugal machine, a motor coupled thereto and capable of being disconnected therefrom, and a screw device, forming an integral part of the framing for moving the motor, substantially as and for the purposes described.

3. In combination with the framing and spindle of a centrifugal machine, a motor for driving same, a clutch coupling the motor thereto, a screwed spindle and nut device between the framing of the machine and the motor, substantially as and for the purposes described.

4. In combination with the framing and spindle of a centrifugal machine, a motor coupled thereto, and capable of being disconnected therefrom, and a screw device for moving the motor, integral with the framing and motor and forming a pivot about which the motor may be turned, substantially as and for the purpose described.

5. In combination with the framing and spindle of a centrifugal machine, a motor for driving same, a clutch coupling the motor thereto, a guide-pillar,a screwed spindle therein and attached to the motor, and a nut on the spindle working in a gap in the pillar, substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES WRIGHT MACFARLANE.
